This invention relatesto'sig-ns and more vparticularly to metal's'igns as displayed 'at street intersections iiiwhiclr a legend bearing V plate-is held-within'the onfinesofa support 7 frame.

Quite commonly'the"signplate is enamelled in colors, contrasting with-wthe lettering, and

' Qrigidlyheld to a support; under such unyieldr ing "conditions variations of 1 contraction and 10 eXpansi'onjoccur, duetojchanges in tempera vvtu're, tending to crack the enamel dishgure the sign and-allow moisture to attack-the metal backing, causingrust and ultimate destruction totake place. p 7 f T Furthermore the ordinary frame embordefredi sign is unnecessarily expensive; due to merit i'sobtai'ned relative to the streets.

' It is therefore'an object of the present in,-

r 'vention to provide a sign having an enamelled plateloosely but securely held within a uni} tary' frame, capableof independent contrac- 7. tion "and -;eXpansi0n -'whereby cracking and peeling of the enamel is almost entirely avold- 'edQaIid'it s edges pr te 5 l I L, D p p 'f ItH r -featureis in the provi o f means ."whereby single or su er osed signs may' be adjusted at" any desirable relative angle and po'sitively jheld against displace V Another purpose produce a sign ofun usual simplicity; having a minimum number p f ,parts and which presentsan attractive ppearance.
